Description
本發明係與線性模組有關，特別是指一種具支撐裝置的線性模組。 The invention relates to a linear module, in particular to a linear module with a support device.
一般工具機上的傳動機構，主要係以一螺桿及一能夠位移地設於該螺桿的螺帽單元所組成，藉由該螺帽單元的位移，讓該螺帽單元所搭載的物件同步位移；另外，為避免當該螺桿長度較長，且在沒有適當支撐的情形下，導致該螺桿產生撓曲現象，因此，該傳動機構會配置有一支撐裝置，使該螺帽單元得以在同一中心線上移動，避免發生加重磨耗、溫升過高、結構變形等缺失，同時可增加螺帽移動範圍，且確保加工的精度。 The transmission mechanism of the general machine tool is mainly composed of a screw and a nut unit which is displaceably arranged on the screw, and the displacement of the nut unit causes the objects carried by the nut unit to be synchronously displaced; In addition, in order to avoid the deflection of the screw when the length of the screw is long and without proper support, the transmission mechanism is provided with a supporting device for moving the nut unit on the same center line. It avoids the loss of heavy wear, excessive temperature rise, structural deformation, etc., and increases the range of nut movement and ensures the precision of machining.
參閱第1圖所示，顯示美國US5,720,202號滾珠螺桿式致動器之一圖式，其主要在螺桿11一側設有一導軌12，並在該螺桿11與導軌12之間跨置有三支撐座13，各支撐座13之間藉由拉索14、15與滑輪16、17、18、19，進行加、減速移動，此為支撐座13部分使用動滑輪的作動原理，使得支撐座13能達到改變運動方向與移動速度，藉以支撐該螺桿11，避免該螺桿11產生撓曲現象。 Referring to Fig. 1, there is shown a figure of a US 5,720,202 ball screw actuator, which is mainly provided with a guide rail 12 on one side of the screw 11 and three supports between the screw 11 and the guide rail 12 The seat 13 and the support bases 13 are moved and decelerated by the cables 14, 15 and the pulleys 16, 17, 18, 19, which is the operating principle of the movable seat 13 in the support base 13 so that the support base 13 can be reached.

然而，由於各支撐座13間的連動係藉由拉索14、15搭配滑輪16、17、18、19來達成，除了結構設計上較為複雜之外，拉索14、15使用一定年限後，其與滑輪16、17、18、19接觸部會慢慢被磨損後疲乏或斷裂，可靠度低，凸顯出後續維護成本提高的缺陷；同時，該專利前案的零組件過多， 造成組裝成本相對提高，且無支撐外蓋(圖上未示)的功能。 However, since the linkage between the support seats 13 is achieved by the cables 14, 15 being matched with the pulleys 16, 17, 18, 19, in addition to the complicated structural design, after the cables 14, 15 are used for a certain period of time, The contact with the pulleys 16, 17, 18, 19 will be fatigued or broken after being worn slowly, and the reliability is low, which highlights the defects of subsequent maintenance cost improvement; at the same time, there are too many components in the patent case.

A slot shoulder 321 is defined on each of the opposite slot walls of the platform pivot slot 32. The mobile platform 30 has two support sliders 33 slidably disposed on each of the guide rails 24. It is worth mentioning that the mobile platform 30 has a set of nuts 34 disposed on the screw 23, and the configuration and the operation manner of the screw 34 and the screw 23 are the same as those of the prior art, and are not the present invention. The focus of the creation, so the detailed structure and action of these components are not detailed.
二該支撐座40，套置於該螺桿23且能夠位移地設在該導軌24，並分別位於該移動平台30的兩端；本實施例中，各該支撐座40皆具有滑設在各該導軌24的二支撐滑塊41。 The support frame 40 is disposed on the screw 23 and is movably disposed on the guide rail 24 and is respectively located at two ends of the moving platform 30. In this embodiment, each of the support bases 40 has a sliding structure. The two rails 24 support the slider 41.
該滾輪50，能夠轉動地設在該移動平台30的平台樞槽32，並具有二第一輪部51、一位於二該第一輪部51之間且輪徑521小於該第一輪部51輪徑511的第二輪部52、及一穿置各該第一輪部51及第二輪部52且兩端分別設置在該槽肩部321的軸部53；本實施例中，該滾輪50的第一輪部51會部分凸出於該平台頂面31，且該第一輪部51與第二輪部52的輪徑511、521比為二比一，如圖7所示。 The roller 50 is rotatably disposed on the platform pivot 32 of the moving platform 30, and has two first wheel portions 51, one between the first wheel portions 51 and a wheel diameter 521 smaller than the first wheel portion 51. The second wheel portion 52 of the wheel diameter 511 and the first wheel portion 51 and the second wheel portion 52 are disposed on the shaft portion 53 of the shoulder portion 321 respectively. In this embodiment, the roller The first wheel portion 51 of the portion 50 is partially protruded from the top surface 31 of the platform, and the ratio of the wheel diameters 511 and 521 of the first wheel portion 51 to the second wheel portion 52 is two to one, as shown in FIG.

以上所述即為本發明第一實施例各主要構件之結構及其組態說明。至於本發明第一實施例的作動方式及其功效，說明如下。 The above is the structure and configuration description of each main component of the first embodiment of the present invention. As for the operation mode and the effect of the first embodiment of the present invention, the following is explained.
其一、由於該滾輪50是能夠轉動地設在該移動平台30的平台樞槽32，且組設後該第一、二輪部51、52會部分凸出於該平台頂面31，而所凸出於該平台頂面31的該第一輪部51會與該外蓋70的外蓋底面72接觸，因此，可支撐該外蓋70，避免該外蓋70因長度過長所產生的撓曲現象，達到降低該外蓋70與該線性模組的移動平台30或支撐座40產生干涉的目的。 First, since the roller 50 is rotatably disposed on the platform pivot 32 of the moving platform 30, and after the assembly, the first and second wheel portions 51, 52 partially protrude from the top surface 31 of the platform, and are convex. The first wheel portion 51 of the top surface 31 of the platform is in contact with the bottom surface 72 of the outer cover 70 of the outer cover 70. Therefore, the outer cover 70 can be supported to avoid the deflection caused by the outer cover 70 being too long. The purpose of reducing the interference between the outer cover 70 and the moving platform 30 or the support base 40 of the linear module is achieved.
其二、由於該移動平台30、及二該支撐座40皆套置於該螺桿23且能夠位移地設在該導軌24，因此，得以避免該螺桿23因長度較長所產生的撓曲現象，達到支撐該螺桿23的基本要求，同時該移動平台30及二該支撐座40之間的連動關係僅透過單一該滾輪50及單一該連接件60所達成，因此組 成構件數量明顯較前述專利前案較少，藉以達到機構簡單、維護成本低的目的。 Secondly, since the moving platform 30 and the supporting base 40 are sleeved on the screw 23 and are displaceably disposed on the guide rail 24, the deflection of the screw 23 due to the long length can be avoided. The basic requirement of supporting the screw 23, and the interlocking relationship between the moving platform 30 and the supporting base 40 is achieved only by a single roller 50 and a single connecting member 60, so the group The number of components is obviously less than that of the aforementioned patents, so as to achieve the purpose of simple organization and low maintenance cost.
其三、由於本發明該移動平台30、各支撐座40、滾輪50、及連接件60構成用以支撐該螺桿23及該外蓋70的支撐裝置，其中該移動平台30及各支撐座40皆可使用剛性結構體，且使該移動平台30及二該支撐座40之間產生連動關的該滾輪50及連接件60在選用上可為一不易變形的塊體及板體，因此，用以支撐該螺桿23及該外蓋70所使用的移動平台30、各支撐座40、滾輪50、及連接件60使用年限得以提高。且本發明在設計上未使用拉索與滑輪，因此降低了結構設計的複雜性，可靠度較佳，後續維護成本較低。 The mobile platform 30, the support base 40, the roller 50, and the connecting member 60 constitute a supporting device for supporting the screw 23 and the outer cover 70, wherein the moving platform 30 and each supporting base 40 are The rigid structure can be used, and the roller 50 and the connecting member 60 which are connected between the moving platform 30 and the supporting base 40 can be selected as a non-deformable block and a plate body. The use time of the moving platform 30, the support base 40, the roller 50, and the connecting member 60 for supporting the screw 23 and the outer cover 70 is improved. Moreover, the invention does not use the cable and the pulley in the design, thereby reducing the complexity of the structural design, the reliability is better, and the subsequent maintenance cost is lower.
其四、複參閱圖6及圖8所示，由於該滾輪50的第一輪部51係與該外蓋70的外蓋底面72接觸、該第二輪部52係與該連接件60的連接底面611接觸、該連接件60兩連接端部61分別固設在二該支撐座40，且該第一輪部51與第二輪部52的輪徑511、521比為二比一，因此，當該螺桿23原地轉動時，該移動平台30隨之位移，當移動平台30移動S距離時，滾輪50會轉動並帶動連接件60反向移動S/2的距離，使得支撐座40移動S/2的距離。 Fourth, as shown in FIG. 6 and FIG. 8 , the first wheel portion 51 of the roller 50 is in contact with the bottom surface 72 of the outer cover 70, and the second wheel portion 52 is connected to the connecting member 60. The bottom surface 611 is in contact with each other, and the two connecting end portions 61 of the connecting member 60 are respectively fixed to the supporting base 40.
